Constructor Detail

ServletExternalContext

public ServletExternalContext(javax.servlet.ServletContext context,
                              javax.servlet.http.HttpServletRequest request,
                              javax.servlet.http.HttpServletResponse response)

Create a new external context wrapping given servlet HTTP request and response and given servlet context.

Parameters:

context - the servlet context

request - the HTTP request

response - the HTTP response

Method Detail

getContextPath

public java.lang.String getContextPath()

Description copied from interface: ExternalContext

Returns the path (or identifier) of the application that is executing.

Specified by:

getContextPath in interface ExternalContext

Returns:

the application context path (e.g. "/myapp")

getDispatcherPath

public java.lang.String getDispatcherPath()

Description copied from interface: ExternalContext

Returns the path (or identifier) of the dispatcher within the application that dispatched this request.

Specified by:

getDispatcherPath in interface ExternalContext

Returns:

the dispatcher path (e.g. "/dispatcher")

getRequestPathInfo

public java.lang.String getRequestPathInfo()

Description copied from interface: ExternalContext

Returns the path info of this external request. Could be null.

Specified by:

getRequestPathInfo in interface ExternalContext

Returns:

the request path info (e.g. "/flows.htm")

getRequestParameterMap

public ParameterMap getRequestParameterMap()

Description copied from interface: ExternalContext

Provides access to the parameters associated with the user request that led to SWF being called. This map is expected to be immutable and cannot be changed.

Specified by:

getRequestParameterMap in interface ExternalContext

Returns:

the immutable request parameter map

getRequestMap

public MutableAttributeMap getRequestMap()

Description copied from interface: ExternalContext

Provides access to the external request attribute map, providing a storage for data local to the current user request and accessible to both internal and external SWF artifacts.

Specified by:

getRequestMap in interface ExternalContext

Returns:

the mutable request attribute map

getSessionMap

public SharedAttributeMap getSessionMap()

Description copied from interface: ExternalContext

Provides access to the external session map, providing a storage for data local to the current user session and accessible to both internal and external SWF artifacts.

Specified by:

getSessionMap in interface ExternalContext

Returns:

the mutable session attribute map

getGlobalSessionMap

public SharedAttributeMap getGlobalSessionMap()

Description copied from interface: ExternalContext

Provides access to the global external session map, providing a storage for data globally accross the user session and accessible to both internal and external SWF artifacts.

Note: most external context implementations do not distinguish between the concept of a "local" user session scope and a "global" session scope. The Portlet world does, but not the Servlet for example. In those cases calling this method returns the same map as calling ExternalContext.getSessionMap().

Specified by:

getGlobalSessionMap in interface ExternalContext

Returns:

the mutable global session attribute map

getApplicationMap

public SharedAttributeMap getApplicationMap()

Description copied from interface: ExternalContext

Provides access to the external application map, providing a storage for data local to the current user application and accessible to both internal and external SWF artifacts.

Specified by:

getApplicationMap in interface ExternalContext

Returns:

the mutable application attribute map

getContext

public javax.servlet.ServletContext getContext()

Return the wrapped HTTP servlet context.

getRequest

public javax.servlet.http.HttpServletRequest getRequest()

Return the wrapped HTTP servlet request.

getResponse

public javax.servlet.http.HttpServletResponse getResponse()

Return the wrapped HTTP servlet response.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
